如何訪問vb.net RadioButtonList中的單選按鈕

Question

我想在填充RadioButtonList時更改RadioButtonList的。我不知道如何在綁定列表時訪問單選按鈕。我需要使用DataBind還是DataBounding事件？如何 ？

Answer 1

使用DataBound事件，然後將填充所有單選按鈕。

Private Sub YourRadioButtonList_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles YourRadioButtonList.DataBound 

    For Each rd As RadioButton In YourRadioButtonList.Items 

     'Or some other condition that determines the CSS Class. 
     If rd.Checked Then 

      rd.CssClass = "NewCssClass" 

     End If 

    Next 

End Sub
